Member Function Documentation
| unsigned long itk::SingleValuedVnlCostFunctionAdaptor::AddObserver | ( | const EventObject & | event, | |
| Command * | ||||
| ) | const |
This AddObserver method allows to simulate that this class derives from an itkObject for the purpose of reporting iteration events. The goal of this method is to allow ITK-vnl optimizer adaptors to get iteration events despite the fact that VNL does not provide callbacks.
| virtual void itk::SingleValuedVnlCostFunctionAdaptor::compute | ( | const InternalParametersType & | x, | |
| InternalMeasureType * | f, | |||
| InternalDerivativeType * | g | |||
| ) | [virtual] |
Delegate computation of value and gradient to the costFunction.
| void itk::SingleValuedVnlCostFunctionAdaptor::ConvertExternalToInternalGradient | ( | const DerivativeType & | input, | |
| InternalDerivativeType & | output | |||
| ) | const |
Convert external derviative measures into internal type
| virtual InternalMeasureType itk::SingleValuedVnlCostFunctionAdaptor::f | ( | const InternalParametersType & | inparameters | ) | [virtual] |
Delegate computation of the value to the CostFunction.

Get the CostFunction deriving from SingleValuedCostFunction
Definition at line 71 of file itkSingleValuedVnlCostFunctionAdaptor.h.
| bool itk::SingleValuedVnlCostFunctionAdaptor::GetNegateCostFunction | ( | ) | const |
Set/Get Negate cost function. The purpose of this boolean flag is to make possible to take certain VNL optimizers that are only minimizers, and use them for maximizing functions. When the boolean flag is set to true, the values returned by GetValue in the internal ITK cost function will be multiplied by -1 before returning it in the f() function. Similar operations will be done for the gradf() and compute() methods. When the boolean flag is set to false, then the values returned by the ITK cost function will be passed unchanged to the VNL optimizers.
| virtual void itk::SingleValuedVnlCostFunctionAdaptor::gradf | ( | const InternalParametersType & | inparameters, | |
| InternalDerivativeType & | gradient | |||
| ) | [virtual] |
Delegate computation of the gradient to the costFunction.
| void itk::SingleValuedVnlCostFunctionAdaptor::NegateCostFunctionOff | ( | ) | [inline] |
Set/Get Negate cost function. The purpose of this boolean flag is to make possible to take certain VNL optimizers that are only minimizers, and use them for maximizing functions. When the boolean flag is set to true, the values returned by GetValue in the internal ITK cost function will be multiplied by -1 before returning it in the f() function. Similar operations will be done for the gradf() and compute() methods. When the boolean flag is set to false, then the values returned by the ITK cost function will be passed unchanged to the VNL optimizers.
